Species composition, ecological and trophic affiliation of weeds in sunflower crops

The article presents practical material, obtained in the result of careful herbologist surveys of crops of sunflower sowings. It is established that in agrocenosis of sunflower the most harmful weeds are common ragweed, pigweed white (sprawling saltbush), canetic Theophrastus, emydoidea amaranth, amaranth thrown back, foxtail glaucous (mice PPE), field bindweed, sunflower Broomrape (top), i.e., complex type of crops contamination - annual-perennial-choreotrichia-parasitic one. In addition, the paper presents the detailed taxonomic, agrobiological and ecological and trophic characteristics of weeds.
Keywords: Sunflower, herbicide, herbological monitoring, sunflower Broomrape, an obligate parasite, perennial weed-forming the weeds, monocotyledonous weeds, dicotyledonous weeds, a root parasite, spring weeds, race formation, nodules, many-stem form of Broomrape
